Description

Multi-color layer processing forming method of full denture and dental tray and material block thereof

The invention relates to a processing and forming method and a block thereof, and in particular to an innovative multi-color layer processing and forming method of a full denture and a dental tray and a revealer of a block structure thereof.

According to the requirements, the need for making full dentures is common in patients who are elderly or lose their teeth due to bad habits (such as smoking, eating betel nut, etc.). The common form of full dentures is the activity of the entire upper and lower jaw. For the conventional denture manufacturing and processing methods, most of them are only processing the bottom part of the gum bed, and the card slot is opened at a predetermined position during processing, and then the commercially available artificial resin tooth products are sequentially processed. It is adhered to the groove of the bottom of the gum bed to complete the complete denture. Although this kind of manufacturing and processing method is common, but it exists: 1. teeth are easy to fall off 2. adhesives are not easy to control and affect the position of artificial resin teeth in the slot 3. errors such as displacement errors are missing; in addition, if artificial The resin completes the complete denture structure in a single process, so it has only a single color (for example, the entire finished product only shows the color of the teeth) and cannot show the color of real human teeth and gums, nor can it be distinguished by the color of human teeth and gums.

In view of the foregoing, the present inventors have been aware of these problems at present, and have been engaged in the production and marketing of related products for many years. They have pondered the improvement methods, and after many improvements and tests, they finally obtained the method and structure of the present invention.

For this reason, the main purpose of the present invention is to provide a multi-color layer processing and forming method, which can present the finished denture and dental tray finished products with soft and hard differentiation and different color configurations at one time through the process of multi-color layer processing. The conventional processing method must lead to errors through adhesion; another object of the present invention is to provide a block, which can be repeatedly and accurately positioned during the processing and forming process by setting the positioning portion of the block, effectively improving the convenience of processing And the accuracy of the finished product.

In order to achieve the above object, the present invention provides a method for processing and forming a multi-color layer of a full denture and a dental tray. The multi-color layer processing and forming method includes: providing a hard color block, the hard color block having a predetermined positioning; Positioning the hard color block at a processing device for the first processing, the first processing is to form a tooth-like structure of a predetermined arrangement type at a local position of the hard color block; forming the first processing Tooth-like structure, after removing the hard color material block, drill a hole at one end of each tooth-shaped structure, and then assemble and fix the hard color material block in an injection mold box; inject a soft rubber into the injection mold box, And the tooth-like structure must be partially covered. The color of the soft rubber material is different from the hard color material block. After the area where the soft rubber material is injected is polymerized, it forms a gum color material block and appears multi-colored. Layer overall structure type; demolding the injection mold box to take out the hard color block, gum color block, and set the position of the hard color block to the processing device; perform the second processing, Include order Tray-shaped block is formed toner gums, thereby presenting the denture heterochromatic finished and tray type.

The invention also provides a material block, the predetermined area of the material block is provided with a positioning The positioning portion includes at least one of a positioning hole, a positioning shaft, a positioning groove, and a positioning margin, or any combination thereof.

The following is further described in conjunction with the drawings of the preferred embodiment of the present invention, in order to enable those familiar with the related technology of the present invention to implement it according to the statements in this specification.

First, please refer to the first to fifth figures. The present invention provides a multi-color layer processing method for full dentures and trays. The multi-color layer processing method mainly includes: providing a hard color material block 10. The hard coloring material block 10 has a predetermined positioning portion 11. The positioning portion 11 includes at least one of a positioning hole, a positioning shaft, a positioning groove, and a positioning margin. The part is not limited; the hard color material block 10 is positioned at a processing device A for the first processing, and the first processing is formed at the local position of the hard color material block 10 to form a tooth-like structure 12 of a predetermined arrangement type; In specific implementation, the tooth-like structure 12 formed by the first processing has a plurality of connecting portions 121 and is connected to the hard color block 10 in a non-shedding form; The hard color block 10 can be repeatedly and accurately positioned to the processing device A by the positioning portion 11 to process the top or bottom face.

The hard color block 10 is assembled and fixed in an injection mold box 13; a soft rubber material (only labeled with the number L in the icon below the fourth figure) is injected into the injection mold box 13, and the tooth shape must be partially covered. Structure 12, the color of the soft rubber material L is different from that of the hard rubber material block 10, and after the area where the soft rubber material is injected is polymerized and formed, it forms a gum color material block 20 and presents an overall structure of a multi-color layer In specific implementation, the hard color material block 10 is made of a composite resin material that mimics the color of teeth, and the soft rubber material is made of plastic material that mimics the color of gums.

The injection mold box 13 is demoulded and the hard color block 10 and gum color block 20 are taken out, and the positioning portion 11 of the hard color block 10 is assembled in the processing device A; the second processing includes: The gum color material block 20 is formed into a tray shape, so as to present a full-color denture and a finished tray shape in different colors. The present invention further provides a material block (that is, the above-mentioned hard color material block 10).

For the description of the main embodiments of the present invention, please refer to the third to fifth figures: the tooth-like structure 12 is formed in the first processing, and the hard color block 10 is removed before the tooth-like structure 12 One end of the structure 12 is drilled with 122, fixed in the injection mold box 13, and the soft rubber material L is injected into the injection mold box 13, the soft rubber material L must be covered and filled with the drill of each tooth-shaped structure 12.孔 122。 The hole 122.

Continuing the above, as far as the present invention is concerned, compared with the conventional processing and forming method, The finished products with real colors also have different soft and hard parts, which can not only greatly improve the quality and exquisiteness of the finished products, but also prevent the finished products from falling off, etc., and can greatly improve the conventional products that are easy to make due to adhesives. There are missing problems such as error displacement, quality and practicality.

To sum up, the present invention can effectively improve the shortcomings of the conventional knowledge, and can achieve the unexpected effects of the conventional knowledge. It is in line with the application requirements of the invention patent, and submitted an application in accordance with the law. right.
